Just one week stands between South Florida’s economic development officials and the deadline to submit a proposal for Amazon’s HQ2, the e-commerce behemoth’s planned headquarters outside of its main Seattle campus. To help move things along, Miami startup Gridics applied its proprietary software to identify a few sites that are worth a look.

Gridics has developed two distinct patent-pending applications to help city governments, architects, urban planners and commercial brokers conduct analyses of parcels. One of these applications is Zonar.City, which found 24 parcels in Miami-Dade County that would fulfill every one of Amazon’s (Nasdaq: AMZN) requirements for HQ2, outlined in a request for proposal (RFP) published by the company in September.

The 24 parcels Zonar.City identified in its report combine into six building sites that could accommodate the 500,000 square feet of space Amazon said it will initially require for HQ2, while also being centrally located and adjacent to resources the company considers essential to its operations and staff, such as mass transit, major highways and universities.

Gridics’ report showcases the parcels as six building sites with varying structure types, ranging from dedicated office towers to mixed-use options.

Building No. 1 would be a combination of two parcels of land across from the Knight Center in downtown Miami, together spanning about 76,500 square feet for a mixed-use high-rise made up of office and commercial space, hotel suites for visiting executives, and residential units for Amazon employees.

Buildings No. 2 and 3, zoned in a different section of downtown Miami, could house a primarily office-oriented building with some street-level commercial retail space. The parcels are clustered within the same four-block radius that faces Bayfront Park.

Building No. 4, “a prime location” that overlooks the bay near the American Airlines Arena, would also house office space, with about 10 percent dedicated to residential and hotel spaces.

Site No. 5, in Overtown, is envisioned by Gridics as a data center or potential logistics hub that would complement other towers identified in the report. While offset from other towers drawn up by Zonar.City, the site adheres to Amazon’s RFP due to its proximity to other sites, a Metrorail stop and entry to Interstate 95.

Finally, Building No. 6 would be 35-level, 716,000-square-foot office tower in Miami’s Omni neighborhood near Museum Park. The site, a combination of three parcels, is accessible primarily by car from Interstate 395, bus stops and Metromover.

Amazon's second headquarters would house as many as 50,000 employees. The deadline for applications is Oct. 19.
